This device is definitely impressively made. I intend to use 1 or 2 on the rear wheels of a 4WD car (Volvo XC70). It's better than being stuck on the muddy Montana desert roads waiting for a friendly rancher or a nuisance. Carefully practice locating the side adjustment holes to clean the rear suspension components and there should be strong traction when needed. Mounting on the front wheels isn't difficult either, but EVERY sharp turn straight ahead will result in very damaging breakage of the fender liner and wheel arch liners. The wrenches are also sturdy and the included rubber gloves are incredibly large.
